I will be spending a year studying abroad in Germany and am unsure of cell phone plans options. I would like to purchase an iPhone I can use for pictures/data. I understand iPhones only work on certain networks (GSM vs CDMA). If I purchase an unlocked phone will I be able to purchase service on a local German network. What is the best German service provider for data plans? Any help you could give would be greatly appreciated, as I am new to this topic.
